The service covers all sorts of uncomfortable situations like breaking up, telling your boyfriend you are pregnant, or any other conversation you don't want to have. Here is a blurb from the website:

I'm the guy you call when you’re pregnant and terrified. I’m the guy you call for the things 911 can’t do. I’m the guy you call when he’s drunk again and you want him out, and never coming back. - Bitter Pillbox

So, don't bother confronting that person, just have someone else do it! It's much easier that way...
